Plant Care Basics

Grow Zone Recommendation: Licorice plant can be grown as an annual or perennial. Since it’s a tropical, it can only be grown as a perennial in zones 9 to 11, but can be grown as an annual in zones 6 to 8.

Sunlight Needs: Licorice can be grown in sun or partial sun. Provide lots of sun in most locations, but in the tropics, it will appreciate afternoon shade.

Watering Needs: Regular, abundant watering is required during the growing season. Water deeply to keep the surrounding soil slightly moist at all times. In wintertime, water should be given less frequently.

Average Size: The size of fully-grown licorice plant is generally 1 to 3 feet tall and 1 to 2 feet in width.

Foliage Color: The foliage of licorice plant can be blue-green, grayish silver, or more golden-chartreuse.

Must Know Plant Care Tips: Licorice can be grown either in the ground or in containers. Either way, you’ll need well-drained and loose soil that is free of rocks. Make sure the hole you plant in is nice and deep. Add compost and sand to clay-like soil. If planting in a container, choose a large pot of light color, so the roots don’t absorb too much heat from the sun. Mix 1 part each of sand, loam, and compost. If you’re in a colder zone, bring your licorice pots indoors for the winter. You’ll want to mulch your plants well, but it doesn’t usually need fertilizer if compost is used.

Plant Problem Solver: Licorice plants are not terribly prone to disease. Spider mites can be a problem, especially during drier times. Spritz the foliage frequently with water to help alleviate this problem. Also watch for powdery mildew, caterpillars, and slugs.

Pretty Pairings: Good companion plants for licorice include rosemary, marigolds, and marjoram. But you might get a weird flavor from your licorice if you plant it near cabbage, broccoli, garlic, onions, or leeks.
